Macroeconomic analysis relies on several different metrics to compare economic productivity and standards of living between countries and across time. One popular metric is purchasing power parity (PPP).

Purchasing power parity (PPP) is an economic theory that compares different countries' currencies through a "basket of goods" approach. According to this concept, two currencies are in equilibrium or at par when a basket of goods (taking into account the exchange rate) is priced the same in both countries.

You're right Mavis. For those who are pressured into unpaid overtime, the minimum wage, taking into account the extra hours, is certainly reduced.

Also, the tax free threshold, which I believe does not exist in US, is a big help to many.
